Bump bumpalo from 2.6.0 to 3.4.0 #158

Closed dependabot-preview[bot] closed 3 years ago

Bumps bumpalo from 2.6.0 to 3.4.0.

Changelog

Sourced from bumpalo's changelog.

3.4.0

Released 2020-06-01.

Added

  • Added the bumpalo::boxed::Box<T> type. It is an owned pointer referencing a bump-allocated value, and it runs T's Drop implementation on the referenced value when dropped. This type can be used by enabling the "boxed" cargo feature flag.

3.3.0

Released 2020-05-13.

Added

  • Added fallible allocation methods to Bump: try_new, try_with_capacity, and try_alloc_layout.

  • Added Bump::chunk_capacity

  • Added bumpalo::collections::Vec::try_reserve[_exact]

3.2.1

Released 2020-03-24.

Security

  • When reallocing, if we allocate new space, we need to copy the old allocation's bytes into the new space. There are old_size number of bytes in the old allocation, but we were accidentally copying new_size number of bytes, which could lead to copying bytes into the realloc'd space from past the chunk that we're bump allocating out of, from unknown memory.

    If an attacker can cause reallocs, and can read the realoced data back, this could allow them to read things from other regions of memory that they shouldn't be able to. For example, if some crypto keys happened to live in memory right after a chunk we were bump allocating out of, this could allow the attacker to read the crypto keys.

    Beyond just fixing the bug and adding a regression test, I've also taken two additional steps:

    1. While we were already running the testsuite under valgrind in CI, because
